City College of San Francisco
San Francisco, CA
The irregular, complex layout of this new 156,000-sq. ft. facility required a lateral structural system comprised of special concentric braced frames and reinforced concrete shear walls supported on a continuous concrete grid footing system. Due to its location at the bottom of a big hill, the project required complicated shoring to accommodate the building’s basement and a partial floor. SOHA designed a sophisticated system of tiebacks and soldier beams to stabilize up to 30 feet of soil. Project included a large gymnasium featuring architecturally exposed long-span tresses, computerized fitness center, dance theater complex, staff offices, student health services and an indoor swimming pool.
